[0002] Coating refers to the process of coating the slurry on the surface of the current collector such as foil and drying the organic solvent in the slurry. It is one of the important processes in the production of pole pieces. In the related technology, the pole piece is usually coated by a coating device. The existing coating device includes a coating roller and a rubber pressure roller. The coating roller and the rubber pressure roller cooperate to extrude the foil. Through the extrusion of the coating roller and the rubber pressure roller, the slurry is evenly coated on the surface of the foil.

In order to reduce the impact of slurry adhesion on the operation of the rubber roller, it is usually necessary to regularly disassemble the rubber roller and clean it manually. When the rubber roller is disassembled and cleaned, the machine needs to be stopped first. Frequent shutdowns and disassembly and cleaning work will consume manpower and increase labor costs, thereby affecting the production efficiency of the electrode. Utility Model Content
